An integral forming rolling process of the ring with convex cone section on outer wall was introduces, which reduced the material consumption of the ring with convex cone section on outer wall and improved the overall quality of the ring. Then, the finite element model of the ring rolling forming was established by software ABAQUS, the rolling forming process were analyzed, and change laws of the Mises stress, inner wall displacement and equivalent strain during rolling process were studied. The results show that at the beginning of ring rolling, due to the uneven stress distribution, the stress changes periodically. After the ring is rolled for 5 s, the stress distribution gradually becomes uniform. During the process of filling the boss with material, the material far away from the boss hole accumulates and becomes higher than the boss hole. There is a difference in strain on both sides of the boss, and it becomes more obvious when the feeding amount is 4.5 mm. The experimental results are close to the simulation results, which verifies the feasibility of the forming process.
